Insert the handpiece body into the sleeve making sure that the optic fiber tip easily slides.
Slide the sleeve to regulate the optic fiber tip. The optic fiber tip must protrude at least 1 cm out
of the disposable tip.
Warning
If the optic fiber tip does not protrude at least 1 cm out of the disposable tip, there is a risk that
the disposable tip will heat up.
Warning
In the event of the sleeve is left inserted for a long time, it could happen that it is "glued" to the
gasket. If it happens, move the sleeve with more strength till the complete removal of the part.
Adjustment of the optic fiber
Notch the optic fiber tip with the blade of the tool.
Bend the optic fiber tip at the notched location. It breaks at the notched location with a smooth,
perpendicular fracture surface.
Notice
Press firmly but do not squeeze the optic fiber tip. Just a little notch is needed to achieve a
perfect result.
Check to see if the aiming beam projects a uniform circular pattern. To do this, aim the optic
fiber tip vertically at a white background located approx. 5 cm away.
If the aiming beam projects no pattern at all, adjust the aiming beam brightness or only an
uneven pattern, cut off another one to two millimeters.
Warning
The aiming beam must not be aimed toward a person's eye. It comprises an intensive light
source even when set to a low power level. Always wear protective goggles.
